CMC Length Out of Tolerance
Fenómeno del problema
Length deviation of CMC products >±0.5mm exceeds the tolerance
Análisis de la causa
CMC shrinkage is unstable, fluctuating ±0.5%; mold dimension design does not consider shrinkage compensation; cooling is insufficient and dimensions are not stabilized
Solución
1)Accurately measure CMC shrinkage and compensate the mold; 2)Fully cool to ensure dimensional stability; 3)Annealing treatment to eliminate post-shrinkage
Conclusión clave
Length out of tolerance is caused by unstable shrinkage; accurate shrinkage compensation is the key
